On demand platforms, together with open mechanisms for exchanging applications, provide the ability to third parties to develop and exchange applications supporting cloud ecosystems. Not only do cloud providers deliver application functionality, an entire ecosystem of independent software vendors (ISVs) is vying with one another to extend application offerings. These efforts make online applications better without additional input, guidance nor funding from the cloud service providing the platform. The platform is a successful mechanism for extending cloud applications, but platforms are limited in terms of extending their own functionality.
